While the 'Plus' suggests it will be an oversized phablet version, leaks claim that it will have a 5.2-inch screen, so not much larger than the original.

Rather than being a big jump in size, the Plus version instead exists to bring improved specs. Reports claim it will sport a 2560 x 1440 pixel QHD display, a beefier camera and a 2.0GHzocta-core MediaTek processor.

The fact that HTC didn't take the M9 Plus to Mobile World Congress suggests it might only launch in select markets, so it may not even make it to British shores.

That's all we know for now but stay tuned, we'll update when hear more.
